Title: Method for recovering monobasic acid
Inventor: HAMANO TOSHIKATSU
IPC: C02F1/44
Filed: 1990-07-13
Abstract: PURPOSE:To efficiently recover nitric acid present as nitrate by adding a polybasic acid to the nitrate and recovering the monobasic acid by a diffusion dialysis method with an anion exchange membrane. CONSTITUTION:A polybasic acid is added to nitrate to be recovered as nitric acid as a monobasic acid and this monobasic acid is recovered by a diffusion dialysis method with an anion exchange membrane. The nitrate returns to nitric acid and can be recovered with the membrane. When a membrane selectively permeable to monovalent ions is used as the anion exchange membrane, the transfer of the polybasic acid is prevented and the rate of recovery of the monobasic acid can be increased. If the recovered acid is permitted to be mixed with some H2SO4, about 100% nitric acid can be recovered as nitric acid radicals.

IPC: H04B1/707
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a direct spread CDMA receiver capable of improving reception characteristics by exactly finding the synchronism of inverse spread timing without improving the sampling rate of A/D conversion to received data. SOLUTION: Concerning this direct spread CDMA receiver, in an A/D converting part 1, a signal received by an antenna and converted into a baseband signal is inputted and sampled at the double chip rate. A matched filter 2 finds the value of correlation with received data while using the spread code of 1/-1 and a delay profile preparing part 3 with interpolation function interpolates this correlation value with a filter or the like. A timing detecting part 4 selects delay profiles in order of sizes and extracts every timing. Inverse spread processing parts 5-7 interpolate spread codes synchronously to the timing signal and inversely spread the received data while using that interpolated value. A synthesizing part 8 performs the RAKE diversity synthesis of the inverse spread signal.

Abstract: PURPOSE:To reduce a crystal defect in an epitaxial layer at a bi-polar IC and to improve a quality, by a method wherein a thin oxidized film is formed on a substrate having an embedding layer therein to pour a channel cut impurity, and the oxidized layer is removed to accumulate the epitaxial layer. CONSTITUTION:An oxidized film mask 7 is formed on a P type substrate 1 to selectively diffuse an N<+> embedding layer 3. The oxidized film 7 is removed by etching, and a thin oxidized film 10 is formed about 1,000Angstrom  or less again. A B- ion is then implanted to a whole surface to form a channel cut layer 11 on a substrate surface. The oxidized film 10 is then removed, an N type epitaxial layer 12 is accumulated, and a V-recess is formed in the epitaxial layer 12 to form an interelement separation structure with an insulating material. Consecutively, an element such as transistors is manufactured. This permits the prevention of contaminating of the surface of the substrate 1 at a time when the channel cut layer 11 is formed by pouring, and enables the reduction in a defect produced in the epitaxial layer 12, which results in enabling the improvement of an element property.

Title: Magnetic recording medium
Inventor: KONDO HIROFUMI
IPC: G11B5/725
Filed: 1985-08-23
Abstract: PURPOSE:To improve wear resistance and running stability under service conditions particularly in a low temp. region by depositing a perfluorocarboxylate as a lubricating agent on a thin ferromagnetic metallic film on a nonmagnetic substrate. CONSTITUTION:The thin ferromagnetic metallic film is formed on the nonmagnetic substrate and the perfluorocarboxylate expressed by the general formula CnF2n+1COOR (n is 6-10 integer, R is a hydrocarbon group of 9-25C) is deposited on the thin ferromagnetic metallic film. The carbon atom number n of the perfluorocarboxylic acid is preferably in a 6-10 range. A lubricating effect is not enough if n is <6 and the perfluorocarboxylate solidifies in the low temp. region and the lubricating effect under the low temp. conditions is debased accordingly if n exceeds 10. Similarly with the carbon atom number of the hydrocarbon group in the ester part, the carbon atom number of R in the formula is preferably 9-25. This medium has the excellent running stability and wear resistance and since the solidifying point is low, there is a high effect when the medium is used at the low temp.
